MC56F8002 interrupt reset MCU

I started a projet on MC56F8002 based on an old code. With the new silicon revision, the MCU is not working properly. After a debugging session, I realized that the MCU reset when an interrupt occurs. If I don't activate interrupts, the MCU do not reset. Here is the line to enable the interrupt __EI(0);. On the old silicon revision (mask 1M53M) there is no problem with interrupts.
